Description

The present invention relates to particles suitable for use in detergents, cleaners and personal care products which have a water-soluble or water-dispersible carrier and active-ingredient-containing microcapeins. Furthermore, it relates to a process for the preparation of such particles as well as washing, cleaning or care agents containing such particles. Finally, it also relates to the use of such in textile laundering or textile treatment.

In the textile laundry, the consumer generally pursues not only the goal of freeing the laundry for hygienic and visual reasons of soiling, but he also wants an added value that goes beyond the mere textile cleaning. This added value can e.g. The reason for this is that the textiles may smell good after washing or that the textiles are cared for during washing so that e.g. a softer feel of the textile results.

Consumers are particularly interested in a pleasant smell of the laundry.

For this reason, and to mask the inherent odor of the laundry detergent, most commercially available laundry detergents contain fragrances. When using conventional detergents, however, often only a relatively weak scent remains on the wash after washing, especially if a tumble dryer is used.

The WO 2005/059083 A1 discloses coated granules having a functional core whose coating contains encapsulated perfumes.

From the WO 2007/115872 A1 are solid textile treatment compositions with a water-soluble carrier, which has a coating of a water-soluble polymer and perfume, wherein the sheath is at least partially coated with a textile-care compound known.

Against this background, it was an object of the present invention to provide a means which enables the consumer to obtain added value in the context of conventional mechanical textile treatment, which goes beyond the mere cleaning of the textiles.

This object is achieved by the subject matter of the invention, namely by a particle according to claim 1, suitable for use in washing, cleaning or care products, comprising a water-soluble or water-dispersible carrier and active substance-containing microcapsules.

Microcapsules as such are known. The diameter of usable microcapsules are in the range of a few nanometers to millimeters. In the microcapsules according to the invention solid and / or liquid active substances are included. Suitable materials for the capsules are usually high molecular weight compounds such as protein compounds (eg., Gelatin, albumin, casein and others), cellulose derivatives (eg methylcellulose, ethylcellulose, cellulose acetate, cellulose nitrate, carboxymethylcellulose and others) and especially synthetic Polymers (eg polyamides, polyethylene glycols, polyurethanes, epoxy resins and others). More details will be given later. The general principle of microencapsulation is known, in particular as the encapsulation of liquid or solid phases by coating with film-forming (eg the abovementioned) polymers which, after emulsification and coacervation or interfacial polymerization, are to be enveloped on the surface to be enveloped

Precipitate material. Active-ingredient-containing microcapsules, e.g. fragrance-containing microcapsules are widely available commercially.

The particles of the invention can be used in particular in the main wash of an automatic washing or cleaning process, in particular as an additive to be dosed in addition to a normal washing or cleaning agent or as an integral part of a detergent or cleaning agent. The particles can be added, for example, together with the detergent or cleaning agent in the drum or the dispenser of a washing machine.

In particular, the active ingredients contained in the microcapsules help to achieve the added value to be realized, which goes beyond the mere cleaning of the textiles. According to the invention, this added value can be manifested in particular in an improved textile scenting, in an improved textile care and / or even in the effecting of cosmetic skin care effects, depending on the choice of the active ingredients implemented.

A particle according to the invention comprises, in addition to microcapsules as an essential ingredient, a water-soluble or water-dispersible carrier. The water-soluble or water-dispersible carrier comprises carbohydrates, in particular selected from dextrose, fructose, galactose, isoglucose, glucose, sucrose, raffinose or mixtures thereof, other water-soluble or water-dispersible carriers, material (s) include inorganic alkali metal salts, organic alkali metal salts, inorganic alkaline earth metal salts, organic alkaline earth metal. metal salts, organic acids, silicates, urea or mixtures thereof.

Such support materials are not only inexpensive, but usually dissolve very well in water. In addition, these materials are odorless.

Suitable materials include inorganic alkali metal salts such as sodium chloride, potassium chloride, sodium sulfate, sodium carbonate, potassium sulfate, potassium carbonate, sodium bicarbonate, potassium bicarbonate or mixtures thereof, organic alkali metal salts such as sodium acetate, potassium acetate, sodium citrate, sodium tartrate or potassium sodium tartrate, inorganic alkaline earth metal salts such as calcium chloride, magnesium sulfate or magnesium chloride , organic alkaline earth metal salts such as calcium lactate, carbohydrates, organic acids such as citric acid or tartaric acid, silicates such as water glass, sodium silicate or potassium silicate, urea and mixtures thereof. Especially it is advantageous if the water-soluble or water-dispersible carrier used is based on carbohydrates at least 80% by weight, preferably at least 90% by weight, in particular at least 95% by weight or even completely.

The usable carbohydrate may be, for example, candy or hail sugar. The use of crystalline sugar allows aesthetically pleasing particles with increased consumer acceptance.

The particles of the invention are characterized in that the carrier is in the form of crystals.

The water-soluble or water-dispersible carrier may also contain mixtures of said materials, e.g. Mixtures of salts, e.g. Sodium citrate and carbohydrates.

When using a water-soluble or water-dispersible carrier consisting of carbohydrates or at least predominantly of carbohydrates, the problem of corrosion in the washing machine is avoided, which could possibly occur especially when using inorganic chloride salts as water-soluble or water-dispersible carrier.

Based on the total particle, the proportion of the water-soluble or water-dispersible carrier in a further preferred embodiment is from 50 to 99% by weight, preferably from 75 to 95% by weight.

be used.

However, most preferred are the fragrances, especially in combination with fabric care fabrics (such as silicone oil, etc.) and / or in combination with skin care agents (such as almond oil, etc.).

When washing textiles, the consumer expects not only a visually perfect cleanliness, but also the absence of any unpleasant odors on the cleaned textiles. A retention of fragrances, which come from detergent and provide a pleasant smell, is perceived as particularly pleasant and enhances the cleanliness impression. Consumers are looking for washed laundry to have a fragrance not just on the product itself and right after it Washing is still noticeable, but in particular on several days on the treated object is perceptible.

However, the amount of perfume resulting from the washing or rinsing process from aqueous solution is e.g. on textiles, often too small to ensure a perceptible fragrance impression even over a long time. Since fragrances are particularly cost-intensive ingredients of detergents and cleaners, one endeavors to use them only in small quantities. The loss of these ingredients (for example in a washing machine) is equally unsatisfactory for the manufacturers and consumers of such agents.

It has now been found that by the use of the particles according to the invention, if they are fragrance-containing, when washing or cleaning the surfaces, in particular of textiles, a particularly advantageous fragrance impression (increased favor / higher intensity / better durability) can be achieved, especially if the used particles contain water-insoluble, fragrance-containing microcapsules.

As fragrances or perfume oils or fragrances (these terms are used synonymously here), individual fragrance compounds, e.g. the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type are used. Preferably, however, mixtures of different fragrances are used, which together produce an attractive fragrance. Such perfume oils may also contain natural fragrance mixtures as are available from plant sources.

It is particularly advantageous to use perfume oils, which are generally associated with certain impressions. A perfume oil may advantageously evoke associations to impressions such as "cleanliness" and "freshness," which are generally associated with the use of detergents. Another perfume oil can advantageously support the impression of "care". It is advantageous, e.g. the fragrances, which give the impression of "care" to incorporate by the majority in the microcapsules and the perfumes, which awaken associations with impressions such as "cleanliness" and "freshness", mostly incorporate outside of the microcapsules in the particle, or vice versa.

Fragrances preferred in the context of this invention, which can be used to advantage to give the impression of "cleanliness" and "freshness", are bergamot oil, tangerine oil, dimethyl anthranilate, aldehyde C 11 (s), dihydromyrcenol, 4- tert-butylcyclohexyl acetate, allylamyl glycolate, tetrahydrolinalool, 6-methyl-gamma-ionone, isobornyl acetate, cyclovertal, ethyllinalool, aldehyde C 12, dynascone 10, limonene, orange oil, isobornyl acetate, eucalyptus oil (globulus), callose, cyclovertal, ethyl 2-methyl butyrate, Tetrahydrolinalool, aldehyde C 10, styrolyl acetate, Otbca, waterfruit base, citronitrile, undecavertol, styrolyl acetate, tartalide and / or dihydromethyljasmonate, in particular but dihydromyrcenol and / or 4-tert-butylcyclohexyl acetate. Accordingly, preferred perfume oils may comprise at least one of the aforementioned fragrances.

For the purposes of this invention, preferred fragrances which can be used to enhance the appearance of a "nourishing effect" are aldehyde C14, decalactone gamma, cyclamen aldehyde, lilial, troenan, canthoxal, citronellol, geraniol, musk, phenylethyl alcohol , Dihydrofloriffone, Dmbca, Phenirat, Phenylethylisobutyrate, Rose Oxide, Jasmelia, Hexylcinnamic Aldehyde (alpha), Jonon beta, Ylang, Cyclohexyl Salicylate, Hexenyl Salicylate (cis-3), Sandelice, Santobar, Bacdanol, Guaiacolite, Iso E Super, Timberol (forte), Norlimbanol , Ambroxan, cinnamyl alcohol, cyclopentadecanolides, nirvanol, Javanol, aldehyde C 11, habanolides, maltol, benzylacetone, coumarin, benzylsalicylate, melonal, galbanum (oil), ethylvanillin, koavone, Ptbca 25 cis, hedione, lilial, dihydrofloriffone, isoraldein, methyl palmitate, Methyl oleate and / or methyl myristate. Accordingly, preferred perfume oils may comprise at least one of the aforementioned fragrances.

According to a further preferred embodiment, the product according to the invention contains at least one fragrance, preferably 2, 3 or more fragrances, from the list galaxolide, dihydromyrcenol, 4-tert-butylcyclohexylacetate, gamma-iso-methylionone, tetrahydro-linalool, hexylcinnamaldehyde, lilial, linalool, Amyl cinnamaldehyde, 6-methyl-gamma-ionone, methyl oleate, neryl acetate, 15-pentadecalactone, phenoxyethyl isobutyrate, phenylethyl methanoate, α-pinenes, β-pinenes, rose oxides, sabinene, anethole, benzoic acid 2-hydroxy-pentyl ester, diphenyl ether, benzophenone, cyclamen aldehyde , α-damascone, decanal, dicyclopentadiene alcohol, allylcyclohexylpropionate, isobornyl acetate, bornylacetate, dihydromethyljasmonate, eucalyptol, n-dodecanol, ethyl palmitate, geraniol acetate, hexyl acetate, n-hexyl salicylate, α-ionone, methyl palmitate, 2-naphthyl methyl ketone, isopropyl myristate, rosephenone, Widdrene, styrallyl acetate, thujopsen, dimethylbenzylcarbinyl butyrate, limonene, dimethylbenzylcarbinylacetate, citronellol, 2-th rt-butylcyclohexanol, caryophyllene, ethyl stearate, tartalide, 2,4-hexadienal, methanoazulene, methyl laurate, methyl myristate, 2-methylundecanal, myrcene, nonanal, nopyl acetate, 15-pentadecalactone, beta-phellandrene, 3-phenyl-2-methyl-propene, Rosacetate, traseolide and / or α-terpineol.

The use of perfume precursors is also very advantageous, preferably when they are contained in the (preferably water-insoluble) microcapsule. A perfume precursor is a compound which releases a desired odor and / or perfume molecule by the breaking of a chemical bond, for example by hydrolysis. Typically, to form a perfume precursor, a desired perfume raw material is chemically combined with a carrier, preferably a slightly volatile or moderately volatile carrier. The combination results in a less volatile and more hydrophobic perfume precursor with improved attachment to fabrics. The perfume is then released by disrupting the binding between the perfume raw material and the carrier, for example, by a change in pH (eg, by transpiration in the Wear), humidity, heat and / or sunlight during storage or drying on the clothesline.

The perfume raw material for use in perfume precursors are typically saturated or unsaturated volatile compounds containing an alcohol, an aldehyde and / or a ketone group. Fragrance raw materials useful herein include any fragrant substances or mixtures of substances.

The silicic acid ester mixtures preferably make up at least 2% by weight of the total amount of fragrance,% by weight, based on all the fragrances of the entire particle. The silicic acid ester mixtures are used in particular in the (preferably water-insoluble) microcapsules.

Particularly suitable perfume precursors are reaction products of compounds comprising at least one primary and / or secondary amine group, for example an amino-functional polymer, especially an amino-functional silicone, and a perfume ingredient selected from ketone, aldehyde and mixtures thereof. The use of such substances, in particular in the (preferably water-insoluble) microcapsules, corresponds to a preferred embodiment of the invention.

If the perfume oil contained in the particle, in particular in the (preferably water-insoluble) microcapsules, further comprises fragrances having a boiling point above 250 ° C and a logP value of ≥ 3.0, so is a preferred embodiment.

The use of such fragrances, especially in the (preferably water-insoluble) microcapsules, allows an even further improvement of the fragrance effect, as far as favor, intensity and durability of the scent impression are concerned.

If the perfume oil contained in the (preferably water-insoluble) microcapsules to at least 1, 5 or 10 wt .-% of fragrances (wt .-% based on the contained in the microcapsules perfume oil) having a boiling point above 250 ° C and a logP value of ≥ 3.0, there is a preferred embodiment. It has been found that particles according to the invention which contain such minimum amounts of perfumes having a boiling point above 250 ° C. and a log P value of ≥ 3.0 in the (preferably water-insoluble) microcapsules have particularly advantageous scent properties. For example, an even longer lasting fragrance impression on the laundry can be achieved.

The octanot / water partition coefficient of a perfume ingredient is the ratio between its equilibrium concentration in octanol and in water. Since the distribution coefficients of the perfume ingredients are often high, e.g. 1000 or higher, they are more conveniently given in the form of their base 10 logarithm, one speaks of the so-called log P value.

The logP value of numerous fragrances is documented; For example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc., (Daylight CIS), Irvine, California, contains numerous logP values, along with citations to the original literature. However, the logP values are most conveniently calculated by the "CLOGP" program, which is also available from Daylight CIS. This program also lists the experimental logP values if they are available in the Pomona92 database. The "calculated logP" (ClogP value) is determined by the fragment approximation according to Harsch and Leo (see Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C. Harsch, PG Sammens, JB Taylor and CA Ransden, Eds., P. 295, Pergamon Press, 1990 incorporated herein by reference). The fragment approximation is based on the chemical structure of each of the perfume ingredients, taking into account the numbers and types of atoms, the atomic bonding ability, and the chemical bond. The ClogP values, which are the most reliable and widely used estimates for this physicochemical property, are preferably used in the present invention instead of the experimental logP values in the selection of perfume ingredients useful in the present invention.

The boiling points of numerous fragrances are eg in " Perfume and Flavor Chemicals (Aroma Chemicals) ", S. Arctander, published by the author in 1969 , incorporated herein by reference.

Other boiling point values can be obtained, for example, from various known chemical manuals and databases. If a boiling point is given only at a different pressure, usually a pressure lower than the normal pressure of 760 mm Hg, the boiling point at normal pressure can be determined approximately with the help of boiling point pressure nomographs such as those in " The Chemist's Companion, AJ Gordon and RA Ford, John Wiley & Sons Publishers, 1972, pp. 30-36 , specified, estimated. Where applicable, the boiling point values can also be calculated by computer programs based on the molecular structure data such as those described in " Computer-assisted Prediction of Normal Boiling Points of Pyrans and Pynoles ", DT Starton et al. Chem. Inf. Comput. Sci., 32 (1992), pp. 306-316 , " Computer-assisted Prediction of Normal Boiling Points of Furans, Tetrahydrofurans, and Thiophenes "(Computer-Aided Prediction of the Normal Boiling Points of Furans, Tetrahydrofurans and Thiophenes), DT Starton et al., J. Chem. Inf. Comput. Sci., 31 (1992 ), Pp. 301-310 , and the references cited therein, and " Predicting Physical Properties from Molecular Structure ", R. Murugan et al., Chemtech June 1994, pp. 17-23 , All publications mentioned above are incorporated by reference.

Irrespective of whether the microcapsules contain fragrances or perfume oil as such, the particle as such may also contain fragrances or perfume oil outside the microcapsules. Accordingly, a preferred embodiment of the invention relates to such a particle which contains a perfume oil outside the microcapsules, wherein preferably the composition of the perfume oil outside the microcapsules differs from the perfume oil optionally contained in the microcapsules.

It is particularly preferred if perfume oil is contained in or on the particles both in the microcapsules and outside the microcapsules. These perfume oils may be the same, but it is preferred if these perfume oils differ in order to generate an additional fragrance impression.

An advantage of the particles according to the invention, which contain in particular fragrance-containing (preferably water-insoluble) microcapsules, is that in particular ordinary perfumed sugar crystals may have the disadvantage that they require rather high perfume concentrations, e.g. to achieve a desired long-lasting scent effect of the treated textiles. The use of (preferably water-insoluble) encapsulated perfume oils, especially with long-lasting properties, enables a more effective and thus resource-saving use of perfume oils.

In addition, a high perfume content can lead to process-technical difficulties in perfume application, in particular with perfume-laden sugar crystals. Due to the limited absorptivity of the crystals, the fragrances can essentially only be applied to the surface, for example in combination with a coating layer. Used to coat the crystals, e.g. used a perfume-PEG melt, the melting point of the PEG is greatly reduced at high perfume content, thus inhibiting the solidification of the mixture. As a result, the formation of a stable coating layer is problematic. Such problems are overcome by our invention.

If the total amount of perfume contained in the particle is from 0.1 to 30% by weight, preferably from 0.3 to 15% by weight and in particular from 0.5 to 7% by weight, based on the total weight Particles, so is also a preferred embodiment of the invention.

If the amount of the perfume oil contained in the microcapsules is from 0.01 to 20% by weight, preferably from 0.05 to 10% by weight, based on the total particles, then again a preferred embodiment of the invention is present ,

A further preferred embodiment of the invention is when the amount of the perfume oil not contained in the microcapsules is 0-10% by weight, preferably 0.05-5% by weight, based on the total particles.

As already stated, the active substances in the microcapsules can also comprise textile care substances. In this way, a provision of detergents or cleaning agents or additives with textile-care properties is made possible. In this way, when cleaning textiles they are not only washed clean, but the textiles to be cleaned are also maintained so that they can be used e.g. get a pleasantly soft grip.

The fabric care agents may be present in the particles of the invention within the microcapsules and / or outside the microcapsules.

A particle according to the invention may advantageously comprise fabric-softening clays as a textile care fabric.

Since textile-softening clays also have a water-softening effect, limescale deposits on the laundry are additionally prevented.

In particular, the softening clay can, however, be applied particularly well outside the microcapsules. If softening clay is to be applied to the particle, it is e.g. it is possible first to coat the water-soluble or water-dispersible carrier with the softening clay and then to apply microcapsules and thermoplastic polymer. Alternatively, a mixture of microcap, softening clay and thermoplastic polymer can be applied. Alternatively, it is possible finally to dust off with fabric-softening clay, which corresponds to a particularly preferred embodiment.

As a fabric softening clay, for example, smectite clay is suitable. Preferred smectite clays are beidellite clays, hectorite clays, laponite clays, montmorillonite clays, nontronite clays, saponite clays, sauconite clays, and mixtures thereof. Montmorillonite clays are the preferred softening clays. Bentonites contain mainly montmorillonites and can serve as a preferred source of fabric softening clay.

Suitable bentonites are sold, for example, under the names Laundrosil® by Süd-Chemie or under the name Detercal by Laviosa.

The amount of fabric softening clay in the particles according to the invention can be, for example, between 0.1 and 10% by weight and preferably 1 to 5% by weight. According to another embodiment, no textile softening clay is contained in the particles according to the invention or only a very small amount, for example <0.1% by weight. A reasonable upper limit can also be, for example, 15% by weight.

A major component that can be used in combination with, or independently of, fabric softening clay is an organic fatty acid softener. This may also be present in the particles according to the invention within the microcapsules and / or outside the microcapsules. The organic plasticizer may consist of anionic, cationic or nonionic fatty chains (C10-C22, preferably C12-C18). Anionic softeners include fatty acid soaps. Preferred organic plasticizers are nonionic compounds such as fatty acid esters, ethoxylated fatty acid esters, fatty alcohols and polyol polymers. The organic plasticizer is most preferably a higher fatty acid ester of a pentaerythritol compound, the term used in this specification to describe higher fatty acid esters of pentaerythritol, higher fatty acid esters of pen-taerythritol oligomers, higher fatty acid esters of lower alkylene oxide derivatives of pentaerythritol, and higher fatty acid esters of lower alkylene oxide derivatives of pentaerythritol oligomers ,

A particle according to the invention may contain, for example, a textile-softening polymer, in particular a polysiloxane and / or a cationic polymer, as potential textile care substance. The fabric softening polymer may be contained in and / or outside of the microcapsules. Suitable cationic polymers include in particular those described in " CTFA International Cosmetic Ingredient Dictionary, Fourth Edition, JM Nikitakis, et al, Editors, published by the Cosmetic, Toiletry, and Fragrance Association, 1991 are described and summarized under the collective name "Polyquaternium". The cationic polymers have a fabric softening, thus textile-care effect, and in addition they can make skin-care contribution. A particle according to the invention may also comprise further suitable textile-care compounds, preferably eg fluorescers, anti-redeposition agents, optical brighteners, grayness inhibitors, anti-shrinkage agents, anti-crease agents, color transfer inhibitors, antimicrobial agents, germicides, fungicides, antioxidants, antistatic agents, ironing auxiliaries, UV absorbers, repellents, impregnating agents.

Furthermore, a particle of the invention contains thermoplastic polymer, preferably in amounts of 0.01-25 wt .-%, in particular 0.05-10 wt .-%. Polyethylene glycols (PEG), polyvinyl alcohols, polyacrylate, PVP or polyester are preferably suitable as the thermoplastic polymer. Particularly suitable are solid at room temperature polyethylene glycols having a melting point of about 65 ° C ± 20 ° C, for example having a melting point of about 60 ° C or e.g. of 65 ° C or e.g. from about 55 ° C.

Furthermore, a particle according to the invention may also comprise water-binding substances. If the particle according to the invention thus comprises water-binding substances, preferably in amounts of 0.1-10% by weight, based on the total particles, the water-binding substance being in particular selected from zeolite, silica, fabric softening clay, starch and / or their derivatives and / or cellulose (derivatives), such as preferably carboxymethylcellulose, so is a preferred embodiment of the invention.

The particle of the invention is characterized in that the water-soluble or water-dispersible carrier is coated with a mixture comprising thermoplastic polymer and microcapsules.

In coating, e.g. also water-binding substances and water may be included.

It is suitable, e.g. an embodiment in which the particle core is formed by the water-soluble or water-dispersible carrier, wherein the core is coated with thermoplastic polymer and microcapsules.

It is preferred that a particle of the invention, i. a thermoplastic polymer-microcapsule-coated particle is further powdered with a powdering agent, particularly comprising zeolite, silica, fabric softening clay (e.g., bentonite), starch and / or its derivatives and / or cellulose (derivatives) such as preferably carboxymethylcellulose. This corresponds to a preferred embodiment of the invention.

In a further possible embodiment of the invention, the particle according to the invention is free of surface-active agents, plasticizers and builders.

The microcapsules which can be used according to the invention may be water-soluble and / or water-insoluble microcapsules, but are preferably water-insoluble microcapsules. The water insolubility of the microcapsules has the advantage that this allows a washing application lasting outgoing separation of active ingredients can be made possible. In particular, it is preferred if the water-insoluble microcapsules are reusable microcapsules, the wall material of the microcapsules comprising polyurethanes, polyolefins, polyamides, polyesters, polysaccharides, epoxy resins, silicone resins and / or polycondensation products of carbonyl compounds and compounds containing NH groups. The term "reusable microcapsules" means those microcapsules which, when attached to textile treated therewith, can be opened or wiped by mechanical rubbing or pressure such that release of contents results only as a result of mechanical action, for example when using a towel on which such microcapsules are deposited, dries hands. Preferably usable microcapsules have average diameters in the range of 0.05 to 500 .mu.m, preferably between 5 and 150 .mu.m, in particular between 10 and 100 .mu.m, for example between 10 and 80 .mu.m. The shell of the microcapsules enclosing the core or (filled) cavity has an average thickness in the range between approximately 0.01 and 50 μm, preferably between approximately 0.1 μm and approximately 30 μm, in particular between approximately 0.5 μm and approximately 8 microns. Microcapsules are particularly easy to squeeze if they are within the ranges given above regarding the mean diameter and the average thickness.

The procedure in microcapsule preparation as such is well known to those skilled in the art. Suitable methods for producing microcapsules are familiar to the person skilled in the art and are described, for example, in US Pat US 3,870,52 , in US 3,516,941 , in US 3,415,758 or in EP 0 026 914 A1 described. The latter describes, for example, the microcapsule preparation by acid-induced condensation of melamine-formaldehyde precondensates and / or their C 1 -C 4 -alkyl ethers in water in which the hydrophobic material forming the capsule core is dispersed, in the presence of a protective colloid. For example, melamine-urea-formaldehyde microcapsules or melamine-formaldehyde microcapsules or urea-formaldehyde microcapsules can be used, for example obtainable from 3M Corporation or BASF. Usable microcapsules are also used in EP 1 244 768 A2 described, to which we refer herewith.

In particle production, the microcapsules to be used can be processed, for example, directly in the dispersion, as they usually occur in the ordinary production process. Possibly. one can modify the dispersion, e.g. thicken and / or adjust the water content of the dispersion so that it contains 5 to 80 wt .-%, preferably 40 to 80 wt .-% microcapsules. It is also possible to previously mix the microcapsule dispersion to be used with water-binding substances. This corresponds to a preferred embodiment of the invention. The slurry can e.g. also be modified by the use of thickeners or by adjusting the water content. On the other hand, one can use the microcapsules as such, i. in dry form and not in dispersed form.

A preferred particle according to the invention is characterized in that the water-soluble or water-dispersible carrier has a particle size in the range from 0.1 to 30 mm, in particular 0.2 to 7 mm and particularly preferably 0.5 to 3 mm, e.g. in the range of 0.8 to 2.5 mm.

As such, the particle may have a particle size in the range ≥ 0.1 to 30 mm, preferably ≥ 0.2 to 10 mm, in particular ≥ 0.5 to 5 mm, e.g. in the range 0.8 to 3 mm.

In order to improve the aesthetic impression of the particles, they can be dyed with suitable dyes. Preferred dyes, the selection of which presents no difficulty to the skilled person, have a high storage stability and insensitivity to the other ingredients of detergents or cleaning agents and to light and no pronounced substantivity to textile fibers so as not to stain them.

A particle according to the invention may also contain a pearlescing agent to increase the gloss. Examples of suitable pearlescing agents are ethylene glycol mono- and distearate (for example Cutina AGS from Cognis) and PEG-3-distearate.

The particles of the present invention may preferably have a bulk density in the range of 300 to 900 g / l or 400 to 800 g / l, for example, in the vicinity of 650 g / l.

If, in step (a), the microcapsules are mixed into the melt together with water-binding substances as aqueous slurry, a preferred embodiment of the invention is present. The slurry can e.g. also be modified by the use of thickeners or by adjusting the water content.

If, in the process according to the invention, the water-soluble or water-dispersible carrier material used in step (b) has previously been premodified by mixing the actual carrier with a fabric softening clay in the presence of textile or skin care compounds and / or in particular in the presence of perfume, another preferred Embodiment of the invention before.

If, in the process according to the invention after step (b), the particle is still powdered with a powdering agent, preferably comprising textile softening clay, another preferred embodiment of the invention is present.

Another object of the present invention is a washing, cleaning or care agent containing particles according to the invention as described above or as obtainable by a method according to the invention.

The particles of the invention can be easily introduced into a solid detergent or cleaning agent. A preferred solid detergent or cleaner may be 0.1 to 20% by weight, preferably 1 to 10 wt .-%, of the particles according to the invention, which are mixed in, for example, simply.

Another object of the present invention is the use of the particles according to the invention, as described above, or the washing, cleaning or care agent according to the invention, as described above, in the textile washing or treatment, preferably in an automatic washing machine.

In addition to the particles according to the invention, the detergents or cleaners according to the invention may preferably also contain surfactant (s), it being possible to use anionic, nonionic, zwitterionic and / or amphoteric surfactants. From an application point of view, preference is given to mixtures of anionic and nonionic surfactants. The total surfactant content of a detergent is preferably above 5% by weight, better above 10% by weight, but advantageously below 40% by weight and particularly preferably below 35% by weight, based on the total detergent.

As nonionic surfactants it is possible to use preferably alkoxylated, advantageously ethoxylated, in particular primary, alcohols having preferably 8 to 18 C atoms and on average 1 to 12 moles of ethylene oxide (EO) per mole of alcohol in which the alcohol radical is linear or preferably methyl-branched in the 2-position may contain or linear and methyl-branched radicals in the mixture, as they are usually present in Oxoalkoholresten. In particular, however, alcohol ethoxylates with linear radicals of alcohols of native origin having 12 to 18 carbon atoms, for example of coconut, palm, tallow or oleyl alcohol, and on average 2 to 8 EO per mole of alcohol are preferred. The preferred ethoxylated alcohols include, for example, C _12-14 alcohols with 3 EO, 4 EO or 7 EO, C _9-11 alcohols with 7 EO, C _13-15 alcohols with 3 EO, 5 EO, 7 EO or 8 EO, C _12-18 -alcohols with 3 EO, 5 EO or 7 EO and mixtures of these, such as mixtures of C _12-14 -alcohol with 3 EO and C _12-18 -alcohol with 7 EO. The degrees of ethoxylation given represent statistical means which, for a particular product, may be an integer or a fractional number. Preferred alcohol ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE). In addition to these nonionic surfactants, fatty alcohols with more than 12 EO can also be used. Examples include tallow fatty alcohol with 14 EO, 25 EO, 30 EO or 40 EO. Nonionic surfactants which contain EO and PO groups together in the molecule can also be used according to the invention. Here, block copolymers with EO-PO block units or PO-EO block units can be used, but also EO-PO-EO copolymers or PO-EO-PO copolymers. Of course, it is also possible to use mixed alkoxylated nonionic surfactants in which EO and PO units are not distributed in blocks, but randomly. Such products are due to the simultaneous action of ethylene and propylene oxide on Fatty alcohols available. In addition, as further nonionic surfactants and alkyl glycosides of the general formula RO (G) _x can be used in which R is a primary straight-chain or methyl-branched, especially in the 2-position methyl-branched aliphatic radical having 8 to 22, preferably 12 to 18 carbon atoms and G is the symbol which represents a glycose unit having 5 or 6 C atoms, preferably glucose. The degree of oligomerization x, which indicates the distribution of monoglycosides and oligoglycosides, is any number between 1 and 10; preferably x is 1.2 to 1.4. Alkyl glycosides are known, mild surfactants. Another class of preferred nonionic surfactants that are used either as the sole nonionic surfactant or in combination with other nonionic surfactants are alkoxylated, preferably ethoxylated or ethoxylated and propoxylated fatty acid alkyl esters, preferably having from 1 to 4 carbon atoms in the alkyl chain, especially fatty acid methyl esters. Nonionic surfactants of the amine oxide type, for example N-cocoalkyl-N, N-dimethylamine oxide and N-tallowalkyl-N, N-dihydroxyethylamine oxide, and the fatty acid alkanolamides may also be suitable. The amount of these nonionic surfactants is preferably not more than that of the ethoxylated fatty alcohols, especially not more than half thereof. The optional content of nonionic surfactants in the washing or cleaning agents is preferably> 0.1% by weight, for example 5 to 30% by weight, preferably 7 to 20% by weight and in particular 9 to 15% by weight, in each case based on the total washing or cleaning agent. In another embodiment, the washing or cleaning agent does not contain any nonionic surfactants or only small amounts, for example <0.5% by weight.

As anionic surfactants, for example, those of the sulfonate type and sulfates can be used. The surfactants of the sulfonate type are preferably C _9-13 -alkylbenzenesulfonates, olefinsulfonates, ie mixtures of alkene and hydroxyalkanesulfonates and disulfonates, as are obtained, for example, from C _12-18 -monoolefins having terminal or internal double bonds by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acid hydrolysis of the sulfonation products into consideration. Also suitable are alkanesulfonates which are obtained from C _12-18 alkanes, for example by sulfochlorination or sulfoxidation with subsequent hydrolysis or neutralization. Likewise suitable are the esters of α-sulfo fatty acids (ester sulfonates), for example the α-sulfonated methyl esters of hydrogenated coconut, palm kernel or tallow fatty acids. Further suitable anionic surfactants are sulfated fatty acid glycerol esters. Fatty acid glycerol esters are to be understood as meaning the mono-, di- and triesters and mixtures thereof, as obtained in the preparation by esterification of a monoglycerol with 1 to 3 moles of fatty acid or in the transesterification of triglycerides with 0.3 to 2 moles of glycerol. Preferred sulfated fatty acid glycerol esters are the sulfonation products of saturated fatty acids having 6 to 22 carbon atoms, for example caproic acid, caprylic acid, capric acid, myristic acid, lauric acid, palmitic acid, stearic acid or behenic acid. Alk (en) ylsulfates are the alkali metal salts and in particular the sodium salts of the sulfuric monoesters of C ₁₂ -C ₁₈ fatty alcohols, for example coconut fatty alcohol, tallow fatty alcohol, lauryl, myristyl, cetyl or stearyl alcohol or the C ₁₀ -C ₂₀ oxo alcohols and those half-esters of secondary alcohols of these chain lengths are preferred. Also preferred are alk (en) ylsulfates of said chain length, which contain a synthetic, produced on a petrochemical basis straight-chain alkyl radical, which have an analogous degradation behavior as the adequate compounds based on oleochemical raw materials. Of washing technology interest, the C ₁₂ -C ₁₆ alkyl sulfates and C ₁₂ -C ₁₅ alkyl sulfates and C ₁₄ -C ₁₅ alkyl sulfates are preferred. Also 2,3-alkyl sulfates, which can be obtained as commercial products of the Shell Oil Company under the name DAN®, are suitable anionic surfactants. Particularly preferred anionic surfactants are soaps. Suitable are saturated and unsaturated fatty acid soaps, such as the salts of lauric acid, myristic acid, palmitic acid, stearic acid, (hydrogenated) erucic acid and behenic acid and, in particular, soap mixtures derived from natural fatty acids, for example coconut, palm kernel, olive oil or tallow fatty acids. The anionic surfactants, including the soaps, may be in the form of their sodium, potassium or ammonium salts and as soluble salts of organic bases, such as mono-, di- or triethanolamine. The anionic surfactants are preferably present in the form of their sodium or potassium salts, in particular in the form of the sodium salts. The optional content of preferred detergents or cleaning agents to anionic surfactants is preferably> 0.1 wt .-%, for example 2 to 30 wt .-%, preferably 4 to 25 wt .-% and in particular 5 to 22 wt .-%, respectively based on the entire detergent or cleaning agent.

In addition to the particles according to the invention and the optional surfactants, the washing or cleaning agents may contain further ingredients which further improve the performance and / or aesthetic properties of the washing or cleaning agent.

The enzymes may be adsorbed to carriers to protect against premature degradation. The proportion of enzymes or enzyme granules directly in the washing or cleaning agent may be, for example, about 0.01 to 5 wt .-%, preferably 0.12 to about 2.5 wt .-%.

In one embodiment, the washing or cleaning agent optionally contains one or more perfumes in an amount of usually up to 10 wt .-%, preferably 0.5 to 7 wt .-%, in particular 1 to 3 wt .-%. The amount of perfume used is also dependent on the type of detergent or cleaning agent. However, it is particularly preferred that perfume is at least partially introduced into the washing or cleaning agent via the particles according to the invention. However, it is also possible for the washing or cleaning agent to contain perfume which is not introduced into the washing or cleaning agent via the particles according to the invention.

Soil-release polymers can usually be used in amounts of between 0% and, for example, 5% by weight, based on the finished washing or cleaning agent. Optical brighteners can usually be found in Amounts between 0% and 0.3 wt .-%, based on the final detergent or cleaning agent used.

A preferred class of complexing agents are the phosphonates, which in preferred detergents or cleaners in amounts of 0.01 to 2.5 wt .-%, preferably 0.02 to 2 wt .-% and in particular from 0.03 to 1, 5 wt .-% are included. These preferred compounds include in particular organophosphonates such as 1-hydroxyethane-1,1-diphosphonic acid (HEDP), aminotri (methylenephosphonic acid) (ATMP), diethylenetriamine penta (methylenephosphonic acid) (DTPMP or DETPMP) and 2-phosphonobutane-1,2 , 4-tricarboxylic acid (PBS-AM), which can be used mostly in the form of their ammonium or alkali metal salts.

In addition, neutral fillers such as sodium sulfate or sodium carbonate may be included in the solid detergents or cleaners.

The washing or cleaning agents according to the invention can be used in particular for cleaning and conditioning textile fabrics.

To prepare the detergents or cleaning agents according to the invention, the detergent or cleaning agent without the particles according to the invention is first prepared by known processes, which may comprise, for example, drying steps, mixing steps, densification steps, shaping steps and / or the subsequent addition of heat-sensitive ingredients ("post-addition") , Subsequently, the product obtained is mixed with the particles according to the invention. For the preparation of detergent tablets, the mixing step may be followed by further compaction and / or shaping steps.
